9-1 Solving Quadratic Equations Using Graphs and Tables – We learned to use a graph to identify the x-intercepts as solutions of a quadratic equation. Then we learned that a quadratic equation can have zero, one, or two real solutions. If the graph of the function has no x-intercepts then the equation has no real solutions. If the graph touches the x-axis but does not cross it then there is only one x-intercept and one real solution.
